Application tiled July 7, 1898l Serial No. 685,418. (No model.)

To a/ZZ whom t may concern:

Be it known that we, HENRY F. PETRAM and EDMUND MASCHEK, citizens of the United States, residing at Ottumwa, in the county of Vapello and State of Iowa, have invented certain new and useful Improvements in Carpet- Fasteners; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it -appertains to make and use the same. Y

The invention has relation to carpet-fasteners; and the object is to provide a simple, inexpensive, and durable device of this character which may be easily attached to the floor and by means of which the edges of the carpetmay be easily engaged therewith.

Vith this object in view the invention consists in certain features of construction and combination of parts, which will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of our improved carpetfastener, showing the pivoted jaw raised. Fig. 2 is a longitudinal sectional View showing the jaw closed.

In the drawings, 1 denotes the body or baseplate of the fastener, having struck up from its sides prongs 2, which are bent downward and are adapted to be driven into the ioorto hold the base-plate in position. The rear end of the base-plate has ears 5 struck up from its edges, between which is pivoted the rear end of the jaw 6, having a downwardlyprojecting lug 7, which when the jaw is folded down is at the rear of a vertical line drawn through the pivot.

8 denotes a iiat spring the forward end of which is formed with upwardly and rearwardly projecting prongs 9, with which the carpet is engaged. The side edges of this spring at its forward end are provided with studs l0, around which are clamped the integral ears 11 at the forward end of the baseplate and by means of which the spring is securely held to said plate. The free or rear end of the spring projects under the pivot and under the lug 7 and exerts its pressure when the sliding jaw is elevated, as shown in Fig. 1, to hold said jaw in that position and enable the carpet to be engaged with the prongs'or points of the spring and when the jaw is depressed, as shown in Fig. 2, to hold the jaw over said prongs and prevent the carpet being accidentally disengaged from said prongs.

From the foregoing description, taken in connection with the accompanying'drawings, the construction, operation, and advantages of the invention will be readily understood without requiring an extended explanation.

By reason of 4its peculiar construction the device may be made at a greatly reduced cost and may be easily secured to the Hoor Without the use of foreign fastening means, such as nails and screws. /Vhen engaged with the floor and the carpet engaged with the prongs of the spring, the carpet will be prevented from becoming accidentally disengaged from said prongs.

Changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

' What we claim is- A carpet-fastener consisting of a base-plate formed with integral downwardly-projecting securing-prongs and with upwardly-projecting lugs at its forward end and upwardly-projecting lugs at its rear end, a spring, the forward end of which is provided with upwardlyprojecting prongs and with studs to be secured by the lugs at the forward end of said plate, a hinged jaw pivoted between the lugs at the rear end of said plate and provided With a downwardly-projecting lug, the rear end of said spring projecting under the lug v of said jaw and adapted to hold said jaw either in an open or closed position, substantially as set forth.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.

HENRY F. PETRAM. EDMUND MASCHEK.
